Design and Treatment Rationale
of the PRO-Active Orthotic

Our orthotic is an ENGINEERED, CUSTOM-FIT orthotic. Many years of research have gone into designing each particular angle in the device, and each angle relates to the next. The foot is treated as a whole and the body as a natural extension of the shock absorption and alignment properties of the properly functioning foot. Our goal is to assess the bone structure of the client, and choose the engineered blank  that best fits that foot. Then the blank is custom fit to the client, keeping in mind that any departure is a departure from the ideal.

The deep heel cup with higher rim and side-wall (thinnest possible construction of heel seat, material designed to thin out and flex at body temperature. By dropping the heel into the cup, the heel fat pad is directed under the point of  the talus for more cushioning. The surrounding  rim and  arch support directly in front of the heel cup prevent the full force of heel strike on talus. (Anytime you raise the heel, you increase heel strike impact AND dump weight onto the front of the foot.) Reducing heel impact reduces the amount of ground force (shock) being sent up the frame. 70% of back pain can be directly related to heel impact.

  • The medium arch height is ideal for the bone structure matching that particular blank. Again, our goal is to have the foot trained to fit the orthotic, not to make the orthotic match the biomechanical problems of the imperfect foot.

  • The metatarsal lift is one of the most effective on the market. Not only is it wide enough to support the whole metatarsal arch, but it initiates far under the metatarsal bones and gently but firmly fans towards the front. Again, the height is the ideal for that particular bone structure. Too low does not give enough support to the plantar fascia ligaments or the metatarsal heads, too high sets the client back on the heel, increasing heel impact and diminishing control of pronation and supination.

  • The properly designed sides of the PRO-Active orthotic control pronation and supination up to 24%.

  • The deep heel cup and sidewall (complete with cup for base of the 5th metatarsal) provide the requirements for the pedorthic rule “Control the heel and you control the limb” ie. Alignment of the ankle, knee and hip.

  • The orthotic is flat on the bottom thereby encouraging the foot to sit flat, in a natural position, and to roll straight through the orthotic, climbing up the arch and metatarsal lift during heel strike to midstance, then pushing off the front of the metatarsal lift  at toe off creating a “roll” instead of “slap” to the client’s gait and exercising and strengthening the ligaments.

We have created a concrete world and as a society are paying the price in chronic pain. Rarely do we walk over natural uneven surfaces that would promote strength and flexibility in our feet and legs. The PRO-Active orthotic provides us with that natural surface and we can ALL benefit from that.
